This is the first year that I'm cosplaying, so I haven't had those moments yet. Though, I do know the the spray on die is just plane EVIL!!!!!!!!!!!
Thankfully, I'll be able to get a wig for my cosplay.
Ah, I can just imagine you yelling down to the people below to watch their heads......"WATCH OUT!!!!!!!! FLYING SPRAY ON HAIR DIE!!!!!!!!!!"
